Thanks for getting back to me. Here are the websites I found:
According to The American Society for Therapeutic Radiology and
Oncology -- ASTRO -- in their information brochure, "What is Radiation
they report the following statistic:
What is Radiation Therapy?
About 50 to 60 percent of cancer patients are treated with radiation
at some time during their disease.
Radiation therapy is the careful use of high-energy radiation to treat
cancer. A doctor (radiation oncologist) may use radiation to cure
cancer or to relieve a cancer patients pain.
A similar figure is given by the American Cancer Society site at their
rediation therapy page:
What Is Radiation Therapy?
Radiation therapy uses a stream of high-energy particles or waves,
such as x-rays, gamma rays, electrons, or protons to destroy or damage
cancer cells. Other names for radiation therapy include radiotherapy,
x-ray therapy, cobalt therapy, and irradiation.
Radiation therapy is one of the most common treatments for cancer and
is used in more than half of all cancer cases.
ACS then goes on to give additional detail about use of radiation
therapies for particular types of cancer:
"It is the primary treatment for some types of cancer, such as certain
non-melanoma skin cancers, head and neck cancers, early-stage
Hodgkin's disease and non-Hodgkin's lymphomas. Cancers of the lung,
breast, cervix, prostate, testes, bladder, thyroid, and brain are also
treated with radiation therapy."
The ACS statement implies there may be more detailed information
available on statistics for treatments of individual cancers. If you
have one particular cancer that's of the most interest, let me know if
you want me to look into it in more detail.
Here's hoping that those who are healthy stay that way, and those who
aren't, get healthy soon....

This was bugging me a bit (well...more than a bit), so I looked around
some more and may have hit paydirt.
An article on radiotherapy that you can see here:
which is called: "When to Consider Radiation Therapy for Your Patient
", cites the 60% figure that I gave you earlier, but actually gives a
primary reference for it:
Perez C, Brady L, eds. Principles and practice of radiation oncology.
3d ed. Philadelphia: Lippincott-Raven, 1998.
I hope this is the "official' source that you needed.
